Try it, you might like it. Didn't think the manufacturer makes much difference, you need a 23.8mm bore if i remember correctly. same as the 2.2 litre turbo 406.

SurGie 54 Posted June 7, 2010 The 406 non abs Bosch is the one to get for quality, it makes the brake bite higher than using the original one. Share this post Link to post Share on other sites
hillbilly 3 Posted June 7, 2010 do the brake lines go in the same as the standerd one? Share this post Link to post Share on other sites
andyjstone 6 Posted June 7, 2010 do the brake lines go in the same as the standerd one? Yes, exactly the same, although if the car was originally a 1.6 you will need to blank off one of the outputs - the Bosch one I bought came with a blanking plug.
